There is a fairly straight forward way to do this, without adding 
specific library into the language.

To borrow an idea for Swift, use a TLS variable as the bottom of the stack.

```d
Something* something;

void userFunc() {
	// Something __temp = Something(something);
	// something = &__temp;
	// scope(exit) something = __temp.parent;

	something.cool(); // actually __temp.cool();
}
```

Implicit temporaries for globals.
